I just read the comments on my books for the first time. I laughed so hard; one person says on "Sugar and Salt" that it is excellent, that she has never read a better book on the subject. Meanwhile, the other one says she found the book so boring and frustrating that she wanted to throw it in the fire! Different strokes.
However, I was sorry that the person who commented on "Flying Butresses" found the second half so disappointing. I worked very hard on that book and hoped to help some folks with it.
All I can do is try.
